Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
170 words
Poly(aryl ethers) having repeating units of the formula --E--O--E'--O-- wherein E is one or more: divalent aromatic radical selected from the group consisting of ##STR104## and E' is one or more divalent radical selected from the group consisting of: E, ##STR105## where A is the group ##STR106## p is an integer and is independently 1 or 2; m is independently 0 or 1 with the proviso that when m is 1 the linkage of the group A to the body of the E radical is via the carbonyl function of the A group, and n is an integer of 1 to 5; T and T 1 can be the same or different and are independently hydrogen, C 1 to C 4 alkyl, C 1 to C 4 alkoxy, phenyl, α-styryl, α-methylstyryl or halogen; Q is independently a chemical bond, O, S, S--S, CH 2 or CO, with the proviso that when E is a naphthylene containing group and both m's are zero and n is one, Q cannot be CO.
Claim 2
Dependent Claim
170 words
Poly(aryl ethers) having repeating units of the formula --E--O--E'--O-- wherein E is one or more: divalent aromatic radical selected from the group consisting of ##STR104## and E' is one or more divalent radical selected from the group consisting of: E, ##STR105## where A is the group ##STR106## p is an integer and is independently 1 or 2; m is independently 0 or 1 with the proviso that when m is 1 the linkage of the group A to the body of the E radical is via the carbonyl function of the A group, and n is an integer of 1 to 5; T and T 1 can be the same or different and are independently hydrogen, C 1 to C 4 alkyl, C 1 to C 4 alkoxy, phenyl, α-styryl, α-methylstyryl or halogen; Q is independently a chemical bond, O, S, S--S, CH 2 or CO, with the proviso that when E is a naphthylene containing group and both m's are zero and n is one, Q cannot be CO.
Claim 3
Dependent Claim
53 words
Poly(aryl ethers) having repeating units of the formula ##STR107## wherein T and T 1 are independently hydrogen, C 1 to C 4 alkyl, C 1 to C 4 alkoxy, phenyl, α-styryl, α-methylstyryl or halogen and Q' is independently O or CO with the proviso that at least one Q' is an oxygen bridge.
Claim 4
Dependent Claim
53 words
Poly(aryl ethers) having repeating units of the formula ##STR107## wherein T and T 1 are independently hydrogen, C 1 to C 4 alkyl, C 1 to C 4 alkoxy, phenyl, α-styryl, α-methylstyryl or halogen and Q' is independently O or CO with the proviso that at least one Q' is an oxygen bridge.
